Best way to slowly replace parajubaea cocoides?

[Mauna Kea Cloudforest]

It's pretty clear that parajubaea cocoides is a very fungus prone palm that just doesn't have long term viability outside of Quito Ecuador. Every year, I see this sort of thing on at least one of the 8 specimens that I grow. They grow right out of it, but still, one of these days I won't be so lucky and mine will end up like Darold's.

I wonder if there is a preventative fungicide that could be used. Which one would folks recommend?

Parajubaea cocoides is a pretty major backbone of my palm landscape, and last year, I decided it was time to take out an insurance policy and transition to parajubaea sunkha and torralyi. But what's the best way of slowly replacing these? I don't want to cut them down until they die.

How about a photo of the planting area(s) in question, that would give us all a better idea of what you're working with

axel as parajubaea cocoides is still an uncommon palm is it not worth trying to box them and sell / trade them giving you the space back and a chance to plant something else

They're far too beautiful to box up and sell. I love them, but they're eventually gonna bite the dust as do all parajubaea cocoides in cultivation outside of their native habitat. While they look nice I want to enjoy them for every bit they have to offer. Would you want to box this up and get rid of it?

The challenge is to have the right backup palm nearby to take over the space. That's basically what I am asking, how close to plant the successor, which would most likely be a tor tor or a tor microcarpa, and in some cases sunkha.

My cocoides are age staggered, so that I will always have at least one or two at various stages of growth, and I will have a p. cocoides in the garden for a long time even if the oldest one starts to die off.

hi axel I agree I wouldn't want to part with them and that being the case I can't see how you can plant replacements until the palms are larger and then under plant with something slower growing like one of the many types of butia or go for faster growth with butia x jubaea hybrids

It would be p. tor, microcarpa or sunkha. Most of them are big enough to under-plant with smaller specimens. I already have a butia, and looks nothing like a parajubaea, so not really suitable.

Axel, how about Beccariophoenix alfredii under that great looking Parajubaea? I think they can take a little shade as long as they have warmth.

Not a bad idea. So far, alfredii seems to be growing in a very similar fashion than parajubaea and it's certainly as hardy as a cocoides. But I'd hate to find out later that they also have a similar fate. It's not a proven palm yet, whereas the other parajubaea species are pretty much bullet proof.

Why not just plant some young P. cocoides under each mature one? They could even be grown off seed your mature ones produce,thus closing the cycle and being,let's say,sustainable. I love the looks of them and yours are fabulous specimen! I have a young one in Pyrgos and hope to add a couple more this spring. My favorite Parajubaea! Let's hope ours live long healthy lives and reach more than 50ft tall before succumbing to anything!
